How long does it take for a UDP connection?
If it takes 150ms for a packet to go one way from Seattle to Sydney, and if the client (the sender) makes only one request at a time from the server (the receiver), then connection establishment and a response would take at least 600ms. On the other hand, if you sent the request over UDP, it could shave 300ms off this wait.
Can you use both TCP and UDP at the same time?
Many applications use both TCP and UDP on the same port, which is pretty handy, but if you’re making a game server and want to make sure the “attack” command gets to the server when client on the mouse you would be better off implementing it using the same UDP socket you use for updates.
Can a server listen to one socket per client?
That said, if you want to deal with one socket per client, you can set a main socket that listens to a “server port”, through which a connecting client can tell the server its own IP address and the port it is using for the connection.
When do I need external trust 123 / UDP?
External trust 123/UDP is only needed if you have manually configured the Windows Time Service to Sync with a server across the external trust. The Microsoft LDAP client uses ICMP ping when a LDAP request is pending for extended time and it waits for a response. It sends ping requests to verify the server is still on the network.
How to send data from a udpclient class?
Create an instance of the UdpClient class and then call the Connect method. You can use any of the send methods provided in the UdpClient to send data to a remote device. Use the Receive method to receive data from remote hosts.
How does UDP differ from a TCP connection?
In UDP, the client does not form a connection with the server like in TCP and instead just sends a datagram. Similarly, the server need not accept a connection and just waits for datagrams to arrive. Datagrams upon arrival contain the address of sender which the server uses to send data to the correct client.
